I'm not quite sure how you intended the original question. But I'll answer and say what I've said elsewhere many times regarding my name.

When I was given the name YoungBlood, I was always the youngest kid in bands. I was 14 and 18 years old playing with guys that were 50yrs old because the we'd share a common interest in that genre of music. It was hard getting a date at 15 listening to Muddy Waters, Howlin' Wolf and Hip Lankchain while all the cute girls in school were listening to Kanye, Brittney Spears or J-Lo. Anyway, I was the young guy in bands and the music I played was/is blues/Soul/R&B. Back in the 60's and that era, it was popular to call the young guy in the band youngblood. Since there was two "official" guys before me in one particular band I played in named youngblood, I used the capitols as YoungBlood to differentiate myself from them and it carried over to when I needed a name for message boards.

In the coming year or two YoungBlood will probably get replaced with OldPlasma though since I'm hardly the new guy on the block as I used to be. Still can be called YoungBuck though as a drunk chick once called me
